The purpose of the present invention is to provide a structure for a cup sleeve in a shape that is easy to handle and manufacture. The present invention forms a flat figure and has an upper side (1), a lower side (2), and left and right side, moreover, a slit (9) according to left and right direction between the upper side (1) and the lower side (2). In a state where a lower part (11) of the slit (9) is curved to one side in a direction approaching the side (3) of the left and the side (4) of the right, an upper part (10) of the slit (9) is curved to the other side. A sleeve form (S′) is formed by the lower part (11) and the upper part (1), and the internal diameter of the sleeve form (S′) is smaller than the maximum diameter of a drinking cup (C) to be maintained. |
